I am just in the process of getting ready to replace my head gaskets on my 2005 6.0 PSD. I find it very confusing going over forums as to what should replace as preventative maintenance. I know that you normally work on 7.3s but would appreciate it if you have a list of to dos.
Also, I know that mentioned once about changing the AC orfice for colder air con and I was wondering if you could let me know what size as I have drained my Freon to get ready to do this job.
